About this project
What does Player2 AI NPC add?
Player2NPC - Your AI Companion in Minecraft!
Ever wished you had a friend in Minecraft who could actually help you? Not just a pet that follows you around, but a true companion who can chop wood, mine ores, and even defend you from monsters?
Welcome to Player2NPC! This mod brings AI to life in your Minecraft world like never before. Powered by the groundbreaking Player2 AI and the PlayerEngine framework, these aren't your average villagers. These are fully embodied AI companions that listen to you, talk back, and interact with the world just like a real player.
This mod is an entry for the Player2 AI Game Jam, created by Goodbird.
Features
- 🗣️ Natural Language Commands: Simply talk to your companion in chat. No clunky commands! Say "I need some wood for a chest" or "can you deal with that zombie?" and watch them spring into action.
- 🤖 Embodied AI Agents: Your companions aren't just chatbots. They have bodies, inventories, and the ability to break and place blocks, use tools, and fight. They truly exist and act within your world.
- ⚡ Plug-and-Play: It just works! Once installed, you're ready to join the world and meet with your first AI friend. No complicated in-game setup required.
- 🎭 Select Your Companions: Browse a cast of unique AI characters in, each with their own personality, appearance, and voice, provided by the Player2 platform. Press the 'H' key (configurable) to open the Character Selection screen and summon/dismiss your favourite characters.
- 🤝 A True Companion: Need help crafting a shield? Ask them. Low on food? Send them hunting. Exploring a dark cave? They'll watch your back. Your companion is a dynamic part of your adventure.
Quick Start & Installation
Getting your AI companion into your world is easy! Just follow these two steps.
